Abstract (en)
In attaining a target vehicle braking force corresponding to a pedal depression force, an assigned braking force is obtained by subtracting a minimum braking force of a hydraulic braking device corresponding to the pedal depression force from the target vehicle braking force. Then, a distributive braking force of the hydraulic braking device is obtained by subtracting an actual regenerative braking force from the assigned braking force. And, a boost ratio of the hydraulic braking device is controlled based on a target hydraulic braking force which is a sum of the minimum braking force and the distributive braking force. Thus, the braking force of the hydraulic braking device is always utilized for attaining the target vehicle braking force. This invention is specially suitable for electric automotive vehicles and hybrid vehicles, having a regenerative braking device in addition to a hydraulic braking device. This kind of motor-driven vehicles perform a cooperative control wherein the ratio of hydraulic braking force and the regenerative braking force is adequately determined to optimize the braking force applied to vehicle as well as the storage of regenerative electric power. <IMAGE>
